Kind of like how it took decades for us to figure out to put wheels on luggage. I'm sure there are tons of things waiting to be invented that people will look back on us eventually and wondering what took us so long to figure out something so obvious.

    My guess is wheels would not have helped when everywhere is dirt and cobblestones. Wheels appeared when we needed them.
